Metal pole with reenforcing pipes



April 18, 1933- E. w. RIEMENSCHNEIDER METAL FOLE WITH REENFORCING PIPESFiled July 5, 1928 Patented Apr. 18, 1933 UNITED STATES PATENT OFFICEEDMUND W. RIEMENSCI-LNEIDER, OF CANTON, OHIO, ASSIGNOR T THE UNION METALl, MANUFACTURING COMPANY, 0F CANTON,v OHIO, A CORPORATION OF OHIO METALPOLE WITH REENFORGING rrrns Application led .Tuly 5,

The invention relates to tubular metal poles and more particularly topoles of this general character which are provided with an internalreenforcing pipe.

Poles of this character are usually installed by first erecting thereenforcing pipe in a concrete foundation, after which the tubular pole,which may be in the form of a cast iron shell, is hoisted up andtelescoped over the pipe, being lowered into position around the sameand attached to the foundation and reenforcing pipe by any suitable andwell known means.

This practice is very expensive, requiring special rigging for hoistingthe tubular shell and lowering it over the reenforcing pipe.Furthermore, it has been found by experience that this method ofinstalling these poles involves considerable danger to the workmen as itfrequently happens that high tension wires or cables are located abovethe point where the pole is erected.

This has resulted in a number of serious accidents in which workmen havebeen killed by accidentally bringing the shell into contact with thesehigh tension wires and the like when the same is hoisted.

The object of the present improvement is to provide a tubular pole withpipe reenforcing which obviates these objections and difficulties inerection, the tubular shell and reenforcing pipe being telescoped andconnected together before they are connected to the concrete foundation.

The above and other objects may be attained by providing a flange ofsteel or the like on the lower portion of the reenforcing pipe andconnecting the same thereto as by screw threads, casting, welding or thelike, and by connecting the upper end of the pipe to the upper portionof the tubular shell by means of a bolt or the like, seating the loweror base port-ion of the tubular shell upon the flange.

The pipe and tubular shell may then be erected as a unit and the flangemay be bolted or otherwise connected to the concrete foundation.

An embodiment of the invention thus set 192s. sel-iai No. 290,366.

forth in general terms is illustrated in the accompanying drawing, inwhich Figure 1 is a vertical sectional view of the` improved pole; f

Fig. 2, an enlarged transverse section taken .c substantially on theline 2-2, Fig. l;

Y Fig. 3, a vertical sectional view of the ,base portion of a modifiedform of the pole; and

Fig. 4, `an enlarged transverse section on the line 4 4, Fig. Y v

Similarnumerals refer to similar parts throughout the drawing. Y

A concrete foundation of any usual and well known construction isindicated generally at 1, having the anchor bolts 2 limbedded thereinwith the threaded extremities 3 thereof protruding above the top of thefoundation. y

The reenforcing pipe 4 may be of any usual construction and in order tocarry out thepresent invention, a flange 5 is fixed to the lower endthereof. This flange may be connected by any suitable -means such aswelding, casting or the like and for the purpose of illust-rationisshown as provided with an internally screw threaded collar 6 screwedupon the threaded lower extremity 7ofthe pipe.

The tubular shell 8 may be of cast iron or the like. and preferably hasthe base portion 9 formed integral therewith. This base may be providedwith the internal annular flange 1() or 10a spaced from its lowerl end,and adapted to rest upon theY upper surface of the flange 5. I

VAn eyebolt 11 may be connected to the up"- per end of the reenforcingpipe as by the pin or bolt 12 located through the eye 13 thereof. Theupper screw threaded end of the eyebolt may be extended through anaperture 14 in thetop wall 15 of the tubular shell 8, a nut 16 beingmounted thereon to connect the shell and pipe together at their upperends and to draw the internal` flangel() of the shell into close contactwith Y the flange 5 of the pipe.

A capital 17 of any desired form provided with lighting fixtures asindicated generally at 18 may be attached to the upper end of i,

the shell, after the same has been erected, as by the screws 19 or thelike.

When the shell and pipe have been connected together as above described,they are then placed in position upon the foundation, the upper ends ofthe anchor bolts 2 extending through suitable apertures 20 in the flange5 and nuts 2l are screwed down upon the threaded extremities of theanchor bolts and into engagement with the flange, holding the pipe andtubular shell rigidly upon the foundation; access tothe threaded eX-tremities of the anchor bolts 2 being had through the opening 23 in thebase portionV 9 for lscrewing the nuts 21 thereon.

As shown in Figs. 3 and t, the iange 10a is of greater Width than theflange 10 in Figs. l and 2, and is provided with apertures 22 arrangedto register with the apertures 20, in the vflange 5, and to also receivethe upper ends of the anchor bolts. The nuts 21 are in this case screweddown upon the iangev 10a and thus positively connect the shell andreenforcing pipe together at their lower ends.

From the above itgwill be obvious that the difficulties and objectionsencountered in the usual practice of erecting tubular poles with pipereenforcements are overcome as there is no necessity for hoisting thetubular pole up above the top of the pipe in order to position the samearound the pipe.

In the present case the pipe and tubular pole are firmly connectedtogether and erected upon the foundation as a unit without requiring anyspecial riging for hoisting the tubular pole into position withoutdanger to the Workmen.

I claim:

A tubular pole, a reenforcing pipe located therein, a hollow baseportion upon the pole, a flange upon th-e lower portion of the pipe andlocated within said hollow base portion,

means projecting from the base for contact with the upper side of theflange, when the upper ends of the pipe and pole are connected together,means connecting the upper ends of the pipe and pole together wherebythey may be erected as a unit, a foundation, and anchor bolts in thefoundation arranged to be connected to the flange on the pipe.

In testimony that I claim the above, I have i hereunto subscribed myname.
